Title: Manufacture of ball joint
Inventor: NOZAWA TOSHIO
IPC: F16C11/06
Filed: 1986-07-10
Abstract: PURPOSE:To increase sufficiently the pull-out load of a stud by inserting a ball stud formed integrally with a spherical head part from the large opening of a housing, and press-fitting a disklike flange into the handle part of the ball stud which has been projected from the small opening. CONSTITUTION:A ball stud 8 has a spherical head part 9 on one end of its handle part, and on the opposite side has a thread part 12 integrally formed. Between the thread part 12 and the head part 9, a neck part 11 having a diameter greater than that of the thread part 12 is formed, and an end surface 15 perpendicular to the axis is formed at the place where the thread part 12 comes in contact with the neck part 11. The ball stud 8, after the head part thereof has been inserted into the bearing member 6 which has been previously fitted in a housing 2, is fixed by a bearing member 7. A flange 13 is press-fitted into the thread part 12 of the ball stud 8 projected from the housing 2 until it is abutted on the end surface 15 perpendicular to the axis. Thus, since the small opening of the housing 2 can be lessened, the pull-out load of the stud can be sufficiently increased.

Title: Automatic controller for operation terminal
Inventor: TAKITA ATSUSHI
IPC: G05B9/02
Filed: 1986-07-14
Abstract: PURPOSE:To prevent disturbance and damage caused by the disturbance from occurring to a plant at the time of the recovery of a driving source (air source) by adding a circuit which makes a command for the degree of opening of an operation terminal coincident with the actual degree of opening when the abnormality of the operation terminal is detected and it is decided that the operation terminal is in a lock state. CONSTITUTION:An abnormality detecting circuit 202 for the operation terminal 61 detects the mutual relation between the opening degree of the operation terminal 61 and a process variable to be controlled or a process variable with close mutual relation because the mutual relation is determined unequivocally in the operation state of the plant. A test and lock deciding circuit 203 inputs a test operation signal to the operation terminal 61 when the abnormality detecting circuit 202 detects abnormality and detects whether there or not is a response to it from variation is process variable, thereby deciding the lock state of the operation terminal. When a decision circuit 203 decides the operation terminal lock state, a reset circuit 204 makes the operation command coincident with the degree of opening estimated from the process variable. Consequently, the degree of opening of the operation terminal 61 is prevented from varying abruptly at the time of unlocking.
